What is the Law of Non Contradiction?


by Rob Lundberg

The Law of Non-Contradiction is the most fundamental law of logic that slam dunks cultural, moral, ethical relativistic thinking.  Relativists posit that all truth is relative, morals are relative, and all religions pretty much say the same “stuff.”

In logical terms, to illustrate this using elementary logical symbols, let’s call a statement, “A.”   Statement A cannot equal the opposite of that statement non A (~A).  So  (A) is not equal to (~A) is a true statement with reference to the law of non contradiction.  Simply stated in practical language, it is not possible for something to be both true and false at the same time and in the same context.

To illustrate that for us, a table cannot be both made entirely of wood and not made entirely of wood. A woman cannot be pregnant and not pregnant at the same time.

Have you ever wondered why we use words like: yes, no, true, false, etc.? You cannot have an answer to a question that is true and false at the same time; nor the answer to a question being yes and no at the same time.  If you try that with your college professor or  high school teacher, getting an answer to a T/F quiz wrong, go to your instructor and challenge that.  I dare.  You will find out the result will not change.

In order to get a glimpse of this in the practical sense, where the law of non-contradiction  is challenged, check out this video.
